TUBIMAR/LLOYDS
TUBIMAR/LLOYDS is a specialised marine exhaust and cooling water hose for yachts and leisure boats up to 24 m. The hose is certified per Lloyd's Register no. 96/00127 (E4), ISO 13363:2004 Type 2 Class B, SAE J 2006:03 R2 and RINA no. DIP061008CS - a combination of British, international and Italian marine approvals. Saltwater and cooling water-resistant construction resists marine exposure over several years of operation. PN 3 bar working pressure and 0.8 bar vacuum with 8 dimensions from ID 40 mm to 127 mm. Typically used on yacht engines, leisure boats and smaller commercial marine installations.

Why this hose?
Lloyd's Register certification is the central element in TUBIMAR/LLOYDS's value proposition. Lloyd's is one of the world's oldest and most broadly recognised classification bureaus (established 1760), and their approval of marine equipment is a broadly accepted qualification on international shipping installations. For yacht owners and leisure boat builders, Lloyd's certification is often part of insurance and registration requirements.
Saltwater-resistant construction is specific to marine applications. Ordinary exhaust hoses (designed for land vehicles) would quickly degrade in saltwater exposure. TUBIMAR/LLOYDS's specific material formulation resists salt spray, saltwater cooling and marine air exposure over several years of operation.
The ISO 13363:2004 Type 2 Class B + SAE J 2006:03 R2 + RINA combination covers broad international standard requirements. This means the hose is acceptable on yachts that sail in international waters - American, Italian, British and European marine authorities all recognise these standards.
Where it is used
Yacht building uses the hose as primary exhaust hose on engine installations. A typical configuration has 5-15 m of TUBIMAR/LLOYDS from engine exhaust port to water injector and further to harbour surface. Lloyd's certification is typically required by insurance companies and marine authorities.
Marine engine test facilities use the hose for quality control of engine installations before delivery. The ISO 13363:2004 qualification is a standard reference for marine engine test facilities, and the hose's long service life makes it a cost-effective solution for continuous test operation.
Marine shipyards use the hose for renovation and maintenance projects on yachts and leisure boats. The wide dimension portfolio (40-127 mm) covers from smaller yacht engines up to larger commercial marine engines.
The hose is colloquially known as a marine exhaust hose, Lloyd's exhaust hose or yacht exhaust hose.

Fields without a value (—) are not specified in the manufacturer's factsheet. Overpressure and underpressure values are recommended operating limits; the product can be subjected to higher loads on request. Bend radius is measured along the inside of the hose bend.
Standards and compliance
The hose is qualified per the central international standards for marine exhaust hoses and marine classification bureau approvals.
- Lloyd's Register no. 96/00127 (E4). British classification bureau approval for marine equipment. One of the world's most broadly recognised marine qualifications.
- ISO 13363:2004 Type 2 Class B. International standard for marine exhaust hoses. Type 2 = wet exhaust systems; Class B = 100 C max temperature.
- SAE J 2006:03 R2. American Society of Automotive Engineers standard for marine exhaust hoses. Broadly recognised on American yacht installations.
- RINA no. DIP061008CS. Italian Naval Register approval. Reference for Italian and European marine installations.
- EN ISO 1307:2008. European standard for rubber and thermoplastic hoses for general use.
- RoHS Directive (2011/65/EU) + REACH (EC 1907/2006). Chemical and environmental regulations.

Industries that use it
TUBIMAR/LLOYDS is used where a Lloyd's-certified marine exhaust hose is required - typically on yachts and leisure boats up to 24 m where international classification bureau approval is part of insurance or registration requirements.
Yacht and leisure boat building is the main market. Marine exhaust systems on leisure boats require specific classification bureau approval (Lloyd's, Bureau Veritas, RINA) as part of insurance and registration requirements. TUBIMAR/LLOYDS is specifically qualified for this use and is a standard solution on modern yacht installations.
Marine engine manufacturing and testing use the hose for quality control applications where specific standard approvals are required. The ISO 13363:2004 + SAE J 2006:03 R2 combination covers most international marine engine standards, and the hose's qualification for these is a direct value addition to the manufacturer's installation.
Marine shipyards and engine renovation use the hose for renovation projects on yachts and leisure boats. Saltwater resistance is critical in marine applications where other hose types will have markedly shorter service life, and Lloyd's certification ensures that the renovation work meets insurance requirements.
Custom lengths and assemblies
The hose can be delivered cut to desired lengths. The standard roll can be supplemented with shorter pieces or multiple rolls by arrangement.

Frequently asked questions
What is Lloyd's Register certification?
Lloyd's Register is a British-based classification bureau (established 1760) that specifically qualifies marine equipment and hoses for use on commercial and commercial-leisure shipping. Certification no. 96/00127 (E4) is Lloyd's specific approval of TUBIMAR/LLOYDS as a marine exhaust hose. It is a broadly recognised qualification that makes the hose acceptable on international shipping installations.
What is TUBIMAR/LLOYDS particularly suitable for?
The hose is a specialised marine exhaust hose for yachts and leisure boats up to 24 m. It handles both exhaust gas and cooling water in marine engine systems - a typical configuration on boat engines where the exhaust pipe transports both exhaust gas and cooling water in the same pipe. ISO 13363:2004 Type 2 Class B and SAE J 2006:03 R2 are the primary international standards.
What does ISO 13363:2004 Type 2 Class B cover?
ISO 13363:2004 is the international standard for marine exhaust hoses. Type 2 specifies hoses for wet exhaust systems (water-injected exhaust). Class B is a specific qualification for 100 C max temperature. The standard specifies material stability, pressure rating, vacuum resistance and service life requirements in marine exhaust gas applications.
How many dimensions are in the range?
8 dimensions: ID 40, 45, 51, 60, 76, 90, 102 and 127 mm. This covers from smaller yacht engines (40-60 mm) up to commercial marine engines (90-127 mm). All have the same pressure rating (3 bar PN, 0.8 bar vacuum) and 20 m standard roll length.
What makes the hose 'saltwater-resistant' (Salzwasserbeständig)?
The factsheet specifies saltwater resistance (Salzwasserbeständig) and cooling water resistance (Kühlwasserbeständig). These are critical properties for marine applications where the hose is continuously exposed to saltwater from the cooling system. The hose's specific material formulation resists salt exposure over several years of operation.
What is the operating temperature?
-30 to +100 C. This covers normal marine exhaust temperatures on yacht and leisure boat engines. The hose is NOT designed for dry exhaust systems (without cooling water) where temperatures can exceed +200 C - for these applications we recommend PROTAPE TPE 326 MEMORY or silicone-based hoses.
Which couplings are recommended?
For marine exhaust systems, stainless steel or bronze couplings (typically DIN 11851, KAMM-Lock or Tri-Clamp) that resist salt exposure are recommended. Standard worm-drive clamps in stainless steel are typically sufficient for 3 bar working pressure. We typically fit couplings to the hose by arrangement.
Is the hose suitable for commercial ships?
The hose is primarily qualified for yachts and leisure boats up to 24 m. For larger commercial ships (above 24 m), specifically qualified large-scale marine exhaust hoses with classification bureau approval (DNV, Bureau Veritas, RINA are typically required) are recommended. RINA approval (Italian Naval Register) is already on TUBIMAR/LLOYDS, but the Lloyd's approval is specifically for the leisure marine segment.
